FUEL-RESERVE'SUPPLY SYSTEM.

Application filed November 18, 1918,

To all whom it may 00 earn Be it known that we, CHARLES l GREEN and linen! LiNnsnY, Jr, residing at Del'iance, county of Defiance, State of Ohio, and Toledo. county of Lucas, State of Ohio respectively, have invented certain new and useful Improvements in Fuel-Reserve-Supply (Systems, of which we declare the following to be a full, clear. and exact description.

)ur invention relates to improvements in fuel reserve supply systems for use particularly in connection with the source from which the fuel is supplied to the engine of motor driven vehicles and has for its object to provide simple and inexpensive means by which the reserve supply is maintained.

A further object of the invention is to provide improved means connecting the fuel supply source with the manifold or carburcter of the engine which will permit the consumption of a predetermined amount of fuel, after which the drivers attention is called to the fact that only the reserve supply or predetermined amount of the main supply remains.

A. further object of the invention is to provide partitioned fuel holding receptacle or adjacent receptacles into which project conduits having means for automatically efili ecting their opening and closing when shifted from one position of adjustment to another in connection with a suction producing apparatus for drawing; the fuel from the receptacle through said conduit.

A. still further object of the invention is to j'HOVidG a plurality of suction conduits adapted to project into separate liquid holding compartments with means for alternately raising and lowering said conduits in said compartments and means for effecting: the alternate opening and closing of the conduits when raised and lowered.

To these and other ends the invention comprises certain novel features of construction and arrangement of parts as will be hereinafter more fully pointed out, it being understood that various changes may be made in the manner of constructing and operating the apparatus without departing from the spirit of the invention.

A structure illustrating one embodiment of our invention is shown in the accompany- Specification of Letters Patent.

Serial No. 262.995.

ing drawings forming part of the specification in which:

.i igure I is a diagrammatic view partly in section illustrating the preferred embodiment of the invention.

F igure II is a fragmentary sectional eleven tion through the fuel supply tank illustrating: the manner of mounting the suction conduits therein.

Figure III is an enlarged fragmentary sectional view showing the manner of construct i115: and mounting" the valves for alternately opening and elosii'igf the suction conduits.

Figure IV is a fr: mentary sectional plan showing the operating; mocha ism for perfecting the raising; and lowering of the conduits, and

l igure V is a sectional plan view on the line of Figure U.

Like letters of reference indicate like parts in the several views in the drawings.

Referring to the drawing, 10 represents any preferred type of engine suitable for motor driven vehicles. the carbureter and manifold thereof being indicated at 11 and 12 re spectively. A vacuum gravity feed tank 13 of any well known (les n is connected with the carbureter and manifold of the engine by means of the conduits i l and 1.5 respectively as sl'iown in Figure the vacuum tank hein gg also connected with the separate fuel compartments 16 ant .ll' of the supply tank 18 by means of the conduits l9 and 20 respectively. The compartments l6 and l? are formed p referably by providing the partition 21 in the tank 18 but may be formed by placing together separate tanks or liquid holding receptacles. As shown in Figure III the conduits 19 and 20 project into the tank upon opposite sides of the partition to points adjacent the bottom of the tank. The conduits at their lower extremities are provided with the valve housings 22 which are preferably screwed upon the conduits and have in their lower ends the fuel inlet openings 23 adapted to be alternately opened and'closed by the valves 24 on the stems 25 which project downwardly from the housings as shown in Fig. III. The stems 25 at their lower ends are provided with heads 26 upon which rest the spring seats 27 for supporting the lower ends of the springs 28, the upper ends of which are seated upon the valve housings or casings 22 as clearly shown in Figure 111.

It will be readily seen that the springs r tain the valves in closed position as long as thestems are out of contact witn the bottom oi? the tank which co-operates with said stems to open the valves whenthe conduits are lowered a predetermined amount.

lpon the top oi the tanlr is provided a plate 29 having at post or standard 30 which is r cessed at 31 to receive spring 32 yieldingly engaging the head 33 oi? a bolt 34L carrying an operating member having a handle 35 and oppositely extending arms 36 projecting loosely into recesses 37 of the lugs or collars secured upon the conduits l9 and 20 as shown in Figure ll.

-The conduits which are slidably mount-- ed in or guided by the plate 29 may be alternately raised and lowered by shifting the lover or pivoted operating member from one position of adjustment to another.

In order that said pivotal member may be held in either of its two positions o'l -adjustment to prevent the accidental shitlting of the conduits within the tank we have provided upon the standard 30 the cam or in clined surface 39st the opposite sides of which are the recesses 40 in one or the other of which the lug or promotion ll on the operating lever normally rests, it being understood that the spring 32 will yieldingly hold the lever in engagement with the standard and prevent the accidental displacement oil? the same and consequently oi? said conduits 'lor the reason that the lug will have to ride over the cam and compress said spring before such displacement can occur.

In the operation oi our fuel reserve supply apparatus at the time the engine is stopped-by reason oi the tact that all oi? the fuel has been used out oi the compartment into which the open conduit is pro jected, the driver is only required to shift the position of the operating lever for the purpose of lowering the opposite conduit at which time the valve thereof will automatically open while the valve ot the other conduit will automatically close to prevent the suction of air thercthro'ug'h. By this means the driver is not required to reset the device when a new supply of iuel is placed in the fuel holding coinpartmeiitsv as the main supply may be drawn from either of said compartments Having thus described our invention, what we claim. as new and desire to secure by Letters Patent is I 1.
